I had always though that the front of the base Z looked a bit off, like something was missing. After seeing some pictures of the INGS+1 front lip, it became my favorite lip out there. It is on the subtler side, and it doesn't protrude in front of the car which is exactly what I wanted.
I struck a deal with deal with Mike (dirTy_shoez), polished it up and installed it.
Fitment: it is dead on. It is a very easy installation process where you bolt it up to two bolts that hold those plastic flaps that are in front of the wheels on. Then you use some 3M VHB tape along the top of the lip, bolt it on then press it onto the bumper so that the tape adheres.
Looks: love it. As I mentioned earlier, I chose this lip because it was clean and on the conservative side. It also flows perfectly with the carbon fiber sport package spoiler I also recently installed and gives the front of the car much more attitude while make the car look visually lower.
Anyway, here are some pictures I took earlier today. Let me know why you think!
